I see. I'm not sure if all of these things are fundamental to TCP itself, but instead are economic and regulatory results. Something to think about. It's not my area so I don't have specific cites, but data centers are effectively meshes. I know there has been work on different ways to transit data within them other than stock TCP/IP. Network coding, for instance, is a pretty cool way to splat data among a whole bunch of interconnected people and UDP to all your peers is a good medium to do it over. There's also work on multipath TCP (MCTCP, others) to help utilize other idle links. I'd check the literature on that, typically under the data center track at networking conferences.
